As a professional platform focused on robotic surgery team training, the VirtaMed RoboS Simulator derives its core value from creating a highly realistic simulation environment that enables seamless transition from skill training to clinical application. The endoscope imaging system, as the core carrier of "visual feedback" in simulated operations, directly affects the authenticity and effectiveness of training. The endoscope camera module built with the OmniVision OV02C10 CMOS color image sensor can provide critical support for the training scenarios of the RoboS Simulator, thanks to its hardware parameters and performance characteristics that accurately match the simulator's needs. Its specific advantages can be analyzed from the following dimensions:
The RoboS Simulator needs to simulate "dynamic operation" scenarios in robotic surgery—such as surgeons performing suture with instruments or bedside assistants adjusting trocar angles. These operations have extremely high requirements for image smoothness and detail clarity. This endoscope module supports 1080P full HD resolution and a maximum frame rate of 60FPS. On one hand, it can accurately capture the movement trajectory of instruments and details of tissue contact, avoiding "dynamic motion blur" caused by insufficient frame rate, and enabling trainees to develop a visual judgment logic consistent with real surgeries. On the other hand, the 2MP pixels combined with the color reproduction capability of the OmniVision OV02C10 sensor can truly replicate the color differences of human tissues, providing accurate visual basis for training links such as "identifying anatomical structures in the surgical area" and "judging operation precision." This aligns with the core goal of the RoboS Simulator—to improve skill transfer efficiency through detailed simulation.
One of the key training contents of the RoboS Simulator is "minimally invasive instrument operation," which requires restoring the movement and field-of-view control of real endoscopes in narrow body cavities. With a lens diameter of only 3.9mm, this module can be perfectly embedded into the minimally invasive instrument simulation components of the RoboS Simulator, replicating the operational logic of clinical endoscopes entering body cavities through trocars. Meanwhile, the combination of the 1/7.25-inch sensor size and 2.78mm maximum imaging circle ensures that while the lens remains compact, "field-of-view limitation" caused by an excessively narrow imaging range is avoided. This allows trainees to not only experience "minimally invasive space constraints" during simulated operations but also cover key surgical areas by adjusting the lens angle appropriately, which is highly consistent with the RoboS Simulator's design concept of "replicating real surgical space constraints."
The differentiated advantage of the RoboS Simulator lies in realizing collaborative training between "surgeons and bedside assistants." The core skills of bedside assistants (such as abdominal positioning and instrument insertion angle adjustment) rely on "wide-angle field of view" and "stable lighting" provided by the endoscope. This module features a 120° wide field of view, which can cover key areas of the "fully sensory abdomen" in the simulator, allowing bedside assistants to clearly observe the relative position between the trocar and the endoscope, as well as the deformation feedback of abdominal tissues, thus avoiding collaboration misjudgments caused by narrow fields of view. At the same time, the 6 integrated 9653 LED beads in the lens can simulate "low-light environments" in body cavities. By adjusting fill light, it replicates the lighting differences of different surgical sites, helping trainees master the clinical skill of "adjusting the field of view according to lighting conditions" and filling the gap in hardware support for "complex lighting scenario simulation" in the RoboS Simulator.
The "basic skill module" of the RoboS Simulator includes "endoscope operation precision training," which requires trainees to achieve field-of-view focusing through manual control. This module supports manual focusing, allowing trainees to practice the operation of "precisely adjusting the endoscope focus" during simulated training, cultivating the "visual-manual coordination" ability consistent with real surgeries, and avoiding the interference of auto-focus on "skill proficiency development." In addition, the module has passed multiple medically recognized tests and certifications such as FCC, CE, Reach, and RoHS, meeting the compliance requirements of the RoboS Simulator as a medical training device. It ensures stable imaging performance during long-term, high-frequency training use and complies with global medical device safety standards, reducing compliance risks in simulator operation and maintenance.
The RoboS Simulator needs to adjust its hardware layout according to training scenarios. This module adopts a split design: it transmits MIPI signals to the DSP board via a Type-C interface, then outputs signals at USB 2.0 speed and supports the UVC protocol. On one hand, this design can flexibly adapt to the "console-simulated body cavity" split architecture of the RoboS Simulator, facilitating the adjustment of the endoscope module's installation position according to training needs. On the other hand, the compatibility of the UVC protocol simplifies the docking process between the module and the simulator's main control system, enabling "plug-and-play" without additional driver development, which reduces the complexity of simulator hardware integration. At the same time, the stable transmission speed of USB 2.0 ensures real-time feedback of image data in the simulator, avoiding the impact of signal delay on training rhythm.
